Title: Improvements relating to image intensifying devices
IPC: H04N5/84
Filed: 1961-09-25
Abstract: 935,403. Television. OPTISCHE INDUSTRIE DE OUDE DELFT N.V. Sept. 25, 1961 [Sept. 24, 1960; Feb. 27, 1961], No. 34311/61. Class 40 (3). [Also in Group XX] An image-intensifying device comprises an electronic image intensifier, an optical objective which projects the final image of said intensifier on to a photographic film, a rapid-processing stage for said film, and means including a light source for obtaining or projecting the image from said film. The device is intended for the intensification of images of low intensity or brightness, and may be embodied in different kinds of apparatus. The embodiment shown in Fig. 2 is an X-ray image intensifier camera. The X-ray image is formed on a fluorescent screen 28, and is reflected via a mirror 29 and a catadioptric objective system on to the photocathode of an electronic image intensifier tube 5. The diminished and brightened image on the anode screen of tube 5 is thrown via an objective 6 on to a film 7, which unrolls from a supply spool 10 on to a take-up spool 27. After exposure in the gate 8, the film passes through a rapid-processing unit 9 consisting of developing and fixing stages, and then through a further gate 19 on its way to the take-up spool. Here it is exposed to a light source 21, and passes between a condenser lens 22 and a projector lens 23. The picture on the film in gate 19 may be inspected directly through a viewer, or thrown on to a screen, or, as is shown in Fig. 2, reflected by mirror 24 to fall on to another film strip 47, which is substantially larger than film strip 7 (e.g. 100 mm. as against 35 mm.). Fig. 1 shows the device embodied in a television camera, for transmission under conditions of poor illumination. The picture is transmitted in a similar manner to that of Fig. 2, via an electronic intensifier tube 5, on to a film 7. If the picture is a still picture, the film exposure may be relatively long. After rapid processing in the unit 9, the light source 21 projects a picture of the film in gate 19 which is reflected on to a pick-up tube 25 such as a vidicon or imageorthicon.
Patent GB-1068304-A (GB)
Title: Fluorescent layers
IPC: G03G5/10
Filed: 1965-08-11
Abstract: A fluorescent layer is made by dissolving a water-insoluble organic phosphor in an hydrophobic organic liquid, dispensing the solution as a colloid into a water solution (continuous phase) of a film-forming binder e.g. gelatin, coating the dispersion on a support, and evaporating the water and organic solvent. Alternatively, the colloidal solution is evaporated, and the dispersion of solid fluorescent compound so obtained is redispensed in water, coated on a support and dried.  An electron-sensitive material, e.g. a silver halide emulsion, may be mixed with the dispersion, or layers of silver halide may be formed above or below the fluorescent layer on the support.  A conductive layer e.g. of cuprous or silver iodide in a resin binder may be formed on the outside of the assembly.  The conductive and electron sensitive layers may be dissolved off during or after development of the image, to leave a fluorescent negative of the electron image, or may remain after development e.g. to act as a "mask" during viewing of the image under an electron beam. Fluorescent materials and corresponding solvents mentioned are: 1,1,4,4-tetraphenyl butadiene (TPR) in cyclohexanone; 1,4-bis-2-(5 - phenyl - oxazolye) - benzene (PoPoP) in cyclo hexanone; p-terphenyl in benzene, anthracene in cyclohexanone; p-quaterphenyl in benzene; and Leucophen B (triazinyl amino stilbene) in cyclohexanone.

[Class 75 (ii).] A light reflector of the inverted-bowl type, designed for uniform illumination of an area long in proportion to its width, comprises two or more optically accurate surfaces 1, 2 for lighting more particularly the comparatively remote areas, the surfaces being surfaces of revolution of curves of the second degree, the foci of which coincide with the light source S and which reflect light back across the common focus in the general direction of their primary axes YS, XS, the remaining surface of the reflector being formed with sufficient precision merely to ensure comparatively uniform illumination between those areas which are lit by reflection from the optically accurate surfaces of the reflector. The surfaces 1, 2 shown in Fig. 3 are paraboloids, and have on their outer surfaces totally reflecting prisms P which extend radially from the apices Y, X, and may be continued over the remaining surface of the reflector. Alternatively, the optically accurate portions 1, 2 may be spherical, and provided on the inner surface, as shown in Fig. 7, with concentric circular prisms P<1> with their centres on the axes of the parts 1, 2, in order to correct for spherical aberration. Instead of totally reflecting prisms being used, the outer surface may be silvered. In this case, when the optically accurate surfaces are spherical, the circular prisms may be on the outer surface. The reflector may be combined with a bowlshaped diffuser, placed beneath the reflector and having fluted or corrugated parts where the beams reflected from the parts 1, 2 of the reflector intersect it. A mould for the reflector is first shaped corresponding to the general intermediate surface, and the parts corresponding to the surfaces 1, 2 are then machined. The mould may be in two or more parts hinged or otherwise connected together.
